Installation Notes

  1. Disconnect the negative battery cable to prevent accidental starting.
  2. Place the outboard in forward gear and remove the lower unit (gearcase) bolts.
  3. Carefully lower and separate the gearcase from the upper housing.
  4. Unbolt and remove the water pump cover to access the impeller.
  5. Note the rotational direction of the old impeller vanes before removing it.
  6. Clean any debris from the pump housing and inspect the wear plate and gaskets.
  7. Install the new impeller, turning the driveshaft clockwise to gently bend the vanes into the correct orientation.
  8. Re-install the water pump cover, applying a light sealant to gaskets if needed and tightening bolts to spec.
  9. Re-attach the lower unit, ensuring the shift shaft, driveshaft, and water tube align correctly.
  10. Reconnect the battery, start the engine with a water supply (flush muffs or in water), and confirm a steady stream from the tell-tale port.

Troubleshooting & FAQ

How can I be sure this impeller fits my specific Yamaha model?

This impeller fits a wide range of Yamaha 100-250 HP engines. The best way to confirm is to check the "Engine & Model Compatibility" table on this page. If your model and year range are listed, it will fit. Verifying your existing part number against our "Part Number Matrix" is also a reliable method.

How often should I replace my water pump impeller?

For preventative maintenance, we strongly recommend replacing the impeller every 100 operating hours or at least once a year, whichever comes first. This helps prevent unexpected overheating and potential engine damage.

What are the signs of a worn or failed water pump impeller?

Common symptoms include the engine overheating at idle or low speeds, a weak or intermittent water stream from the "tell-tale" outlet, and in critical situations, an engine overheat alarm sounding from your console.

What is the difference between this impeller and the original Yamaha OEM part?

This is an aftermarket part designed to meet or exceed OEM specifications. It is made from high-quality neoprene rubber, similar to the original, offering comparable performance and durability at a better value.

Do I need to buy a full water pump repair kit?

This listing is for the impeller only. If your water pump housing, wear plate, or gaskets show signs of scoring, warping, or damage, purchasing a complete water pump repair kit is recommended for a comprehensive service.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

Shipping speed & cost

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.

Safety & Important Info

  • Verify images and specifications against your original part before ordering. If anything differs—even if your model appears compatible—do not purchase.
  • This is an aftermarket replacement component, not an OEM part. Brand names and part numbers are used for identification purposes only.
